I seriously doubt that it causes _noticeable_ lack of fidelity. I think it should work with only one conversion step in any case, as the TIF contains jpg tiles. In theory it should even work without any conversions as it should be possible to tile the raw jpg block data. I googled a bit and it looks like nobody has done this before. Such a tiler has the potential to be both faster and more memory efficient.
In fact JPEG has the image split in blocks, which are compressed separatedly. It should be possible to extract them.
That takes time, about a minute. After that the image is cached and the viewer appears immediately. Be warned, there is no visual feedback that anything is happening while the image is processed. So be patient and try a reload after waiting a minute or so.
If there's it should show a page saying "Please wait while we process the image" with a timer. I get "502 Bad Gateway" and "download wip.php" messages, which probably come from the processing.
It should fallback to javascript vieweer in case there's no javascript support.
You should have built iipimage with FILESYSTEM_PREFIX
I'll write a gadget to integrate this into commons (the gadget will only appear on images with a certain minimum size).
In that case I think you should remove the dependancy on googleapis.com
Good work. Are the wikimedia-specific pieces available?
